The presentation in this paper is the efficient hybrid Dual Full-Bridge DC-DC Converter for the Radio Frequency (RF) power applications. Since there is a drawbacks of a large circulating current at primary side and large output filter size in a conventional Phase-Shift Full-Bridge (PSFB) converter, this hybrid Dual Full-Bridge DC-DC Converter is proposed in order to overcome those draw backs. This proposed converter, at primary side uses a small structure of series capacitor and at a secondary side a two additional diodes that are low voltage rated are adopted together with the full bridge…mehr

The presentation in this paper is the efficient hybrid Dual Full-Bridge DC-DC Converter for the Radio Frequency (RF) power applications. Since there is a drawbacks of a large circulating current at primary side and large output filter size in a conventional Phase-Shift Full-Bridge (PSFB) converter, this hybrid Dual Full-Bridge DC-DC Converter is proposed in order to overcome those draw backs. This proposed converter, at primary side uses a small structure of series capacitor and at a secondary side a two additional diodes that are low voltage rated are adopted together with the full bridge rectifier. This resulting structure of a proposed converter gives an advantage of circulating current reduction, providing the operation of Zero-Voltage Switching for reduction in output, all primary switches, inductor size and offers low conduction loss for the rectifier stage. Moreover, in a very wide range, the output voltage can be regulated by operational mode using this proposed converter. The total load efficiency of converter is improved as a result of above advantages
